Overview
Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity due to an inefficient algorithmic complexity issue in the mjson parsing library when analyzing JSON content, such as with the json_query or jwt_payload_query function. An attacker can cause resource exhaustion and disrupt service availability by sending specially crafted JSON payloads that trigger excessive processing.
